Settle the body with slow breath and stillness

Pair physical stillness with a slow, extended exhale to deepen the rest.

Why it works

Holding the body still removes movement-driven arousal, and lengthening the exhale increases parasympathetic (vagal) activity, slowing heart rate. Together they nudge the nervous system toward the calm state yoga nidra is built around — one of the few fast, reliable physiological levers on arousal.

How to do it

1. Settle into stillness and let the body be heavy and unmoving.
2. Breathe so the exhale is noticeably longer than the inhale, gently and without strain.
3. Keep the breath easy — the lever is the slow, long exhale, not big, forceful breaths.

Evidence

Slow-paced breathing with extended exhales reliably raises heart-rate variability and reduces self-reported stress across multiple studies and a growing meta-analytic literature. (rct)

Effects are real but acute and modest; this regulates state in the moment rather than resolving underlying stress.

Common mistake

Over-breathing or forcing deep inhales, which can raise arousal — the effective move is the slow, extended exhale.
